' Application filed September 10, 1928. Serial No. 304,927.

after more specifically set forth, claimed and I shown in theaccompanying drawings form ing a part of the present application and inwhich: e V

Fig. 1 is a view of the bottle with a cut away section showing theinterior mechanism.

Fig. 2 is a sectional plan view.

Referring more in detailto the drawings in which similar referencecharacters designate corresponding parts. throughout, itv

will be seen that the bottle 3 has acircular flange 4 on the inner sideof the neck, and immediately above this flange is a cross piece 5similarly made into the bottle neck. Into the center of the flange 4 isfastened a flanged ring 6. A circular trapdoor shaped member 7 is hingedto this ring at 8 thus forming the complete check valve. Through thecenter of the check 7, a wire or string 9 is fastened having on thelower end a weight 10 which may be a metal or glass ring or some othersuitable shaped weight. This weight will cause the check 7 to closewhenthe bottle is in any upright or horizontal position providi ing thatthe weight is not low enough to touch the sides when the bottle is in ahorizontal position. To the top of the check 7 a string 11 is looselyfastened the purpose of this string is to hold the check up while thebottle is being filled, and is fastened in such a manner that it may bewithdrawn entirely When the bottle has been filled. The cross-piece 5 isto prevent the check 7 from opening too far and to prevent the mechanismfrom being otherwise tampered with.

It is believed that the construction and advantages of the structureshown may be apparent from the foregoing paragraphs taken in connectionwith the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it isunderstood that minor changes inthe details of construction, combinationand arrangementof cooperating elements may be resorted to within thescope of hat is claimed, without departing from the spirit of theinvention.

lVhat I claim:

In a bottle, an annularflange disposed within the neck thereof; saidflange being integral with said neck and inwardly directed therefrom; aring bearing with the margin of said flange, said ring adapted. toconstitute a seat; a flap-valve hinged to said ring in a manner to bearupon and coact with said seat; a Weight suspended from said flap tonormally close the same and a cross-piece disposed within said neck andintegral therewith, said cross-piece being positioned above saidflap-valve in a manner to limit the opening movement of the flap as andfor the purpose specified.
